OPERATING THE DEVICE
Multi Channel support:
Heatit Z-TRM2fx has support for the
Multi Channel Command
Class
, and can therefore be seen as many devices by the
Z-Wave Controller. Where each of the devices has association
groups in order to send information to other Z-Wave devices,
see the chapter concerning association groups.
The first Multilevel device reports the temperature for the
external temperature sensor.
Second Multilevel device reports the temperature for the floor sensor.
Commands sent to each of the logical devices will be
interpreted according to the description in the section:
Supporting Command Classes.
No Multi Channel support:
If the Z-Wave Controller, or the Z-Wave devices that shall be
associated with Heatit Z-TRM2fx, does not support the
Multi
Channel Command Class
(Multichannel encapsulation), then
only the association groups in the root device is accessible. This
device will contain 5 association groups. For further information,
see the chapter concerning association groups. The root device
is the actual thermostat device.
Supporting Command Classes:
Besides the mandatory command classes, Heatit Z-TRM2fx has
support for following command classes:
•
Basic Command Class.
A
Basic Set
to the root endpoint or endpoint 1 will change the
Thermostat Mode.
•
Binary Switch Command Class.
Sends
Binary Switch
Set commands to other devices when the
internal relay is switched. It can be used to control other slave
relay devices.
•
Thermostat Setpoint Command Class.
When a
Thermostat Setpoint Set
command is received by the
root device, it can set the actual setpoints for the three different
modes the thermostat is able to operate in; Setpoint for the
heating mode, setpoint for cooling mode and the setpoint for
energy saving mode.
•
Thermostat Mode.
It is possible to change the operating mode of the thermostat
by sending a
Thermostat Mode Set
command. This way it is
possible to set the operating mode to: Heating Mode, Cooling
Mode or Energy Saving Mode.
Security:
Heatit Z-TRM2fx is able to operate in security S0 and S2 mode,
this requires that the device is added in security mode during
the inclusion process.
It has a QR-code label that can be used when the module is
included into the Z-Wave home network. The including
Controller will ask for a 5-digit code, which can be identified
beneath the QR-code, and will then ask to confirm the rest of the
code that is contained in the QR-code.
NODE INFORMATION FRAME
The Node Information Frame is the business card of a Z-Wave
device. It contains information about the device type and the
technical capabilities. The inclusion and exclusion of the device
is confirmed by sending out a Node Information Frame. Beside
this, it may be necessary for certain network operations to send
out a Node Information Frame.
ASSOCIATIONS
Z-Wave devices control other Z-Wave devices. The relationship
between one device controlling another device is called
association. In order to control a different device, the controlling
device needs to maintain a list of devices that will receive
controlling commands. These lists are called
association
groups
and they are always related to certain events (e.g.
sensor reports, ...). In case the event happens all devices stored
in the respective association group will receive a common
wireless command.
